U.S. Investment Immigration Focus on U.S. Finance and Economics: On December 12, 2013, the U.S. Department of Energy announced an investment of $226 million to support NuScale Power in conducting technical research and development and license applications for small-scale nuclear power. This is the second small-scale nuclear power funding project announced by the U.S. Department of Energy. As part of the Obama administration's strategy to accelerate clean energy, the U.S. Department of Energy announced a $450 million research funding program in March 2012 to assist the U.S. nuclear industry in the research, development, and licensing of small modular reactors. In March 2013, one year after the funding program was announced, the U.S. Department of Energy announced the first small-scale nuclear power funding project, with Babcock & Wilcox receiving $150 million (or up to $225 million) in funding.
In the Obama administration's clean energy strategy, 80% of U.S. electricity is to be provided by clean energy, including nuclear power, by 2030. Through this large-scale funding for small-scale nuclear power R&D, it is evident that even after the Fukushima nuclear accident, the Obama administration still holds high hopes for achieving its clean energy goals through the development of small-scale nuclear power.
Seizing Industry Leadership
Clearly, the development of small-scale nuclear power has become an important part of the Obama administration's clean energy policy. According to forecasts by the U.S. Energy Information Administration, to meet the goal of 80% of electricity coming from clean energy by 2035, the U.S. will need at least 1,100 TWh of electricity from small-scale nuclear power, a generation scale that exceeds the output of the more than 100 existing nuclear power plants in the U.S. At the same time, small-scale nuclear power is also considered by the U.S. industrial sector as an excellent choice for replacing retired power plants and enhancing grid regulation capabilities. "They can effectively increase the grid's regulation capability because they can increase capacity according to actual needs, and they can also be used to replace retired and aging fossil fuel power plants," former U.S. Secretary of Energy Steven Chu wrote in an article for The Wall Street Journal introducing small-scale nuclear power.
"Small modular reactors are a new generation of safe, reliable, low-carbon energy technology, and they provide an important opportunity for the United States to occupy a leadership position in the global low-carbon industry," U.S. Secretary of Energy Ernest Moniz said at the project funding announcement, "The U.S. Department of Energy is committed to strengthening the importance of nuclear energy in America's low-carbon future, and new technologies like small modular reactors will ensure that we maintain a leading position in the global nuclear energy industry."
The U.S. is funding small-scale nuclear power R&D on such a large scale precisely because it hopes to accelerate its nuclear renaissance strategy through the development of small-scale nuclear power and quickly seize leadership in this field globally. In the agreements signed between the U.S. Department of Energy and small-scale nuclear power companies, it is explicitly stipulated that the designed reactors must be produced domestically to enhance U.S. manufacturing capabilities and increase U.S. export capacity. According to the U.S. Department of Energy's plan, small-scale nuclear power will achieve commercialization around 2025, at which time the U.S. will become a global leader in the small-scale nuclear power industry. According to forecasts by relevant U.S. agencies, between 2019 and 2030, the small-scale nuclear power industry could provide approximately 1.8 million jobs and generate about $280 billion in exports.
Small-scale nuclear power, also known as small modular reactors, is a new form of nuclear energy utilization. Its scale is only one-third or less of existing commercial nuclear power plants, and it features high flexibility, high safety, and low investment. Small-scale nuclear power is suitable for countries and regions with small electricity demand and weak grid infrastructure, and can also be used for power supply in remote areas, residential and industrial heating, offshore oil extraction, seawater desalination, and other fields, holding very broad market prospects. According to the International Atomic Energy Agency, the global demand for small-scale nuclear power will reach 1,000 units by 2040.
Through modular design, small-scale nuclear power can complete the production and assembly of the entire reactor in a factory, and then be transported by truck or train to the destination for power generation. After the end of its service life, the entire reactor can be transported to a reprocessing site for decommissioning. Regarding this highly innovative design scheme, Dr. Daniel Ingersoll, Director of Research and Development at NuScale Power and a former nuclear engineer at the Oak Ridge National Laboratory, said in an interview with U.S. media, "We are looking for a revolutionary form of energy."
Due to the smaller scale, the safety of small-scale nuclear power can be greatly improved. In NuScale Power's small-scale nuclear power design scheme, the probability of core melt is far lower than that of large nuclear power plants (the core melt probability of NuScale small-scale nuclear power is approximately 10^-8, while the core melt probability of second-generation nuclear power plants currently in operation is approximately 10^-5, and the core melt probability of third-generation nuclear power plants currently under construction is approximately 10^-7). In addition, the nuclear fuel load of this type of small-scale nuclear power is only 5% of that of large nuclear power plants, and its impact on the surrounding environment is far less than that of existing commercial nuclear power plants.
Also due to the smaller scale, the investment amount for small-scale nuclear power is significantly reduced, and the construction cycle can be effectively shortened. In existing small-scale nuclear power design schemes, the investment amount ranges from several hundred million to several billion RMB, and the construction cycle can be shortened to 2 to 3 years. In contrast, traditional large-scale nuclear power plants generally require an investment of over 10 billion RMB, and the construction cycle takes as long as 4 to 5 years. Reduced investment and shortened construction cycles greatly increase the attractiveness of small-scale nuclear power investment projects, making it possible to use private capital to invest in nuclear power. Moreover, through mass production, the production cost of small-scale nuclear power can be effectively reduced, thereby improving its economic benefits. This cost control method has already been verified in the U.S. naval shipbuilding industry.
"Commercialization" Four-Step Strategy
Regarding how to successfully achieve the commercialization of small-scale nuclear power, U.S. scholars have provided a "four-step" strategic plan.
Step 1: Accelerate technical verification and license applications. Small-scale nuclear power belongs to a new type of nuclear power technology. For engineers responsible for nuclear power design and technical reviewers at the U.S. Nuclear Regulatory Commission (NRC) responsible for issuing construction licenses, this is entirely new content. They need time and funding to carry out relevant experimental research and technical development. The purpose of this funding project by the U.S. Department of Energy is to provide financial security for small-scale nuclear power development companies to conduct technical verification and license applications.
Step 2: Complete the construction of the first reactor. As the first batch of small-scale nuclear power plants to be produced and built, they will not be able to enjoy the cost advantages brought by "mass production," and high construction costs may become the main obstacle to the construction of the first batch of small-scale nuclear power plants. The U.S. Department of Energy may become the first purchaser of small-scale nuclear power. It can purchase these small-scale nuclear power plants through government public facilities, national laboratories, or military bases under its jurisdiction. In fact, the U.S. Department of Energy signed a memorandum of understanding with three small-scale nuclear power development companies in March 2012 to provide these three companies with services such as land use and site data.
Step 3: Achieve large-scale production. After completing the construction of the first reactor, relevant manufacturers will have the production capacity for small-scale nuclear power. At this stage, the main task of each small-scale nuclear power development company is to carry out financing and expand production capacity. It is expected that by 2030, the U.S. small-scale nuclear power production capacity could reach 20 units per year.
Step 4: WorldWayization. Through the implementation of the previous three steps of the strategy, the United States will form a mature small-scale nuclear power industrial system. At this stage, each small-scale nuclear power development company will actively target domestic and foreign markets and develop toward WorldWayization. It is expected that by 2040, the U.S. small-scale nuclear power production capacity will stabilize at around 50 units per year.
Although there is still debate about the development prospects of the commercial application path for small-scale nuclear power, and although the actual construction costs and economic competitiveness of small-scale nuclear power are still difficult to determine, the resolute measures taken by the U.S. Department of Energy demonstrate the U.S. authorities' great confidence in this new nuclear power technology. Once the commercial application strategy for small-scale nuclear power is successfully implemented, the renaissance of U.S. nuclear energy will be just around the corner!
